This report will examine some of the safety issues involved in the use of water as a furnace coolant, explore some of the alternative furnace coolants, and the design considerations required to use them successfully. This report will also suggest various active and passive strategies to achieve a higher level of safety for plant equipment and more importantly the personnel. 

However, this approach may turn out to be suboptimal, because ultimately interventions are judged on their own merit. Focus, coherence, effectiveness and efficiency can be dealt with when designing a strategy (document) and defining tasks for stakeholders, resulting in their commitment. Management literature tells us that organizations execute policies more effectively if they can do so stand-alone. However, poor coordination remains a critical issue for effective road safety policies and deserves special attention. This is one of the considerations on which the development of the Safe System approach was based. 

This chapter presents an overview and recent advances of nanocomposites for scaffold-based mnscnloskeletal tissue regeneration. Critical design considerations of nanocomposites are discussed with a focus on the efforts to achieve optimal cell-material interactions. It further reviews different fabrication strategies to engineer nanocomposites for musculoskeletal tissue regeneration. 

Models for the corrosion process point to the fact that hot face temperature is the most important variable in controlling refractory life. To reduce corrosion loss, the usual approach is to employ higher-purity refractories or lower-porosity refractories (such as fusion cast brick) because precise limits on hot face temperature are not practical given process goals. In new furnace designs, consideration should be given to hot face temperature control as a strategy to attain the most economical refractory cost. 

A proposed product development process that facilitates designing capable and reliable products has been outlined above. It must be stressed that the product development process itself will not produce quality products, and consideration of many issues are crucial to success, such as company strategy, management structure, commitment, sufficient resources, communication, and most importantly proficient engineering practices, such as the following. 

Signal-flow graphs are particularly useful in two respects. First, they make the process designer examine in considerable detail the dynamic structure and fimctioning of the process. Second, the nature of the interface between person and machine can be seen more clearly. The variables that are displayed in a system are, of course, available for study, but workers frequently respond to derivative functions of variables or "hidden" variables that must be deduced. Given that the process variables to be displayed will influence the worker s control strategy and that the number of deductions to be made will affect the mental workload involved, a process designer can select the type and amoimt of process information which will enhance performance of the task.
